To all who mat may concern:

Be it known that 1, WILLIAM Fl. Jonnsron, a citizen of the United Fatates, and a resident of C "lie-ago, in the county of Cook and State of Illinois, have invented certain new and useful linprovemcnts in Curtain-Windows for. Vehicles, of which the following is a full, clear, and exact description.

The invention relates to curtain-windows for vehicles and its object is to provide a structure of the general character exemplified in Letters Patent No. 1,298,593, in which an ol'itside-frame is dispensed with. The outside frames have been made of metal and in some instances it has been found to be objectionable to have any metallic exterior frame in the curtain.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof. f

In the drawings: Figure 1 is a perspective of a portion of an automobile top embodying the invention. Fig. 2 is a vertical sec-.

tion. Fig. 3 is a side elevation of the curtain-frame, the inner and outer curtainmembers being shown in section. Fig. l is an enlarged detail section through the frame, transparent plate and curtain. Fig. 5 is a detail perspective of the frame. Fig. 6 is a detail perspective of the transparent plate.

Fig. 7 is a perspective of the welt secured in.

the frame. Fig. 8 is an enlarged section on line 8-43 of Fig. 5. Fig. 9 is a detail of one of the corrugated nails. Fig. 10 is a detail section of a modification.

The invention is illustratedas applied to the back 10 of a vehicle-top 11. This back usually comprises inner and outer members A of suitable fabric, usually of different flexible material, as well understood in the art. A. frame 12 is built up of strips of wood 13, the contiguous ends of which are provided with interfitting tongues and grooves i l and the lapped ends of these strips are secured together by corrugated nails 15 which are driven into place after the strips have been fitted together. If desired, the ends may be glued together to additionally secure them so as to form a frame corresponding to the contour of the window desired. A frame thus built up will be substantially rigid which is of especial advantage when no metallic or outside frame is used. The frame ext-ends continuously around the window and the opening therein determines the shape ofthe window. it. substantially right-angled rabbet 16 is formed in the inner corner of the frame and extends continuously around the inside of the frame, thus providing an internal peripheralsurface 1.? and a marginal face 18. The frame is also formed with a projecting half-round bend 19 which extends continuously around its outer side and leaves a reduced outer marginal portion 20. This frame may, if desired, be connected by flexible tie-straps 21 tothe frame of the top or other part of the body of the vehicle. The outer curtain fabric 22. is cut with an opening corresponding generally to the opening in the frame and so as to leave a margin around the opening, which will fit around, as at 9.2, the inner portion of the head 19 and lap the inner face 18 of the rabbet in the frame, as at 23. This fabric is then drawn snugly around the bead and its margin 23 is secured to said face 18 by tacks 24. A. transparent plate 526 with a beveled edge 27 is cut to it into the rabbet of the frame, its bevel fitting against the margin23 of the outer cur ainanember A. An opening is cut into the inner fabric fr conformably to the opening in the frame and so as to leave a margin 28 adapted to be inturned and to lap the inner peripheral surface 1? of the frame. After this margin has been inturned to lap surface 17, a welt 30 is fitted into the rabbet, with one side pressing against the inner face of plate 26 and its outer face bearing against the margin 28 of the fabric A. While the welt is pressed firmly into place, it is secured in positionto secure the plate and the margin 28 of fabric A. in the rabbet of the frame, by tacks 31 which are driven outwardly through the welt and margin 28 and into the frame. The welt consists of a strip of leather or rubber and is preferably covered with fabric to match the fabric A.

The invention exemplifies a curtain window in which a retaining frame on the outside of the curtain is dispensed with. Also one in which a frame is built up of strips of wood and secured together so that an additional reinforcing frame is not necessary. The purpose of the bead 19 is to keep the outer margin and face of the frame away from the fabric A so that this fabric will not become worn by the frame from the swaging of the window. This outer fabric is usually made of Waterproof material which will deteriorate by rubbing contact with a frame, and this bead overcomes this.

If desired, putty may be put. in the corner of the rabbet to provide an outer bearing,

for the margin of the glass plate. In the modification shown in Fig. 10, the margin 28 of fabric A is extended around the outer edge of th glass plate.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appendedtciaims, without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent,is:

1. In a curtain- Window, the combination of a frame having an opening therein and provided with a rabbet in its inner periphery, inner and outer curtain-members between which the frame is disposed, each having an opening therein and the margin of its opening lapped over and secured to one of the faces of the rabbet, a transparent plate in said opening with its margin in'said rabbet and lapping the inner portion of the frame, and a welt secured in the rabbet, the margin of the plate being disposed and secured between the welt and an integral portion of the frame. 7 7V 2. In a curtain-window, the combination of a frame having an opening therein and provided With'a rabbet in its inner periphe ery, an inner curtain fabric having an opening therein and its margin lapped over and secured on the peripheral surface of the rabbet, an outer fabric having an opening and its margin lappedover and secured to the otherface of the rabbet, a transparent plate having its margin in the rabbet, and awelt secured in the rabbet against the plate and the margin of the inner fabrics, the margin of the plate being disposed and held between the welt and an integral portion of the frame.

3.In.a curtain-Window, the combination of .axframe having an'opening therein, and provided With a rabbet in its inner periphery, an inner curtain fabric having an opening therein and its margin lapped over the peripheral surface of the rabbet, an outer fabric having an opening and its margin lapped over theother face of the rabbet, a transparent" plate having its margin in the rabbet, means extending through the margin of the outer fabric and into the frame to secure it to the frame, means for securing the inner fabric to the frame extending through the fabric and into the frame, and a welt secured in the rabbet, and holdingthe plate against the margin of the outer fabric.

4:. In a curtain-window, the combination of a frame having an opening therein and provided with a rabbet in its inner periphery, an inner curtain fabric having an open ing therein and its margin lapped over the peripheral surface 'of'the rabbet, an outer fabric having an opening and its margin lapped over the other face of the rabbet, a transparent plate having its margin in the rabbet, meansexten-cling through the margin of therouter fabric and into the-frame to secure it to the frame, a welt in the rabbet and against the plate and margin of the inner fabric, and securing devices extending through the Welt and margin of the inner fabric and into the frame;

5. In a curtain-window, the combination of a frame having an opening therein, acurtain secured to the frame and in said opening, and a transparent plate secured in said frame, the frame being provided with a projecting head on its face adjacent the curtain and aroundlits inner edge to separate the outer portion of the curtain from the same face of. the frame; 7

6. In a curtain window, the combination of a frame having anopening therein, and a rab et therein, inner and outer curtain-members having margins lapping and secured to the surfaces of the rabbet, and a transparent plate secured in the rabbet, the frame being provided with a projecting bead on-its face adjacent the outer curtainmember and around its inner edgeto separate the outer portion of the samefaceof the frame from the outer curtain member. 3 WILLIAM R.
